JAMES G. ROBERTSON, OF NEW YORK, N. Y.

HEEL.

Specification of Letters Patent.

Patented Dec. 13, 1921.

Application filed May 20, 1918. Serial No. 235,487.

To all whom it may concern:

Be it known that I, JAMES G. ROBERTSON, residing at New York, in thecounty and State of New York, have invented certain new and usefulImprovements in Heels, of which the following is a specification.

This invention relates to heels, and the prime object thereof is toprovide a heel which will remain straight through use.

Another object of the invention is to provide a device designed to beused upon the heel of a boot or shoe, such that it will insure an evenwearing of the heel during its frictional contact with the ground.

Another object of the invention is to provide a device of the abovecharacter designed to be used upon the heel of a boot or shoe, such thatthe appearance of the heel is not changed, the device beingsubstantially invisible when the boot or shoe is being worn.

Other objects and aims of the invention, more or less specific thanthose referred to above, will be in part obvious and in part pointed outin the course of the following description of the elements,combinations, arrangements of parts and applications of principles,constituting the invention; and the scope of protection contemplatedwill be indicated in the appended claims.

In the accompanying drawing, wherein I have illustrated a preferred formof embodiment of my invention:

Figure l is a plan view, showing the bottom surface of the heel equippedwith my improved device.

F i 2 is a sectional view taken on line II-II of Fig. 1; and

Figs. 3 and at are perspective views, showing the details ofconstruction.

Referring now to the drawings, wherein similar reference charactersrefer to similar parts, the reference numeral 1 denotes the body portionof the heel to which my improved device is attached. 2 denotes a supportwhich is interiorly of the heel, preferably near the center portionthereof, said support being pointed so that it may be driven throughseveral of the layers of leather of which heels are commonlyconstructed. The support 2 is provided upon its upper end with a head 3,which is received in a centrally disposed socket 4. of a circular casing5, said casing being provided with a disk-shaped bottom wall 6 and anupstanding rim 7. Portions 8 of the easing are struck downwardly andinwardly so as to engage the lower surface of the head 3 of the support2, whereby said parts are fastenedtogether. While the casing is held inposition upon the heel it has a rotative movement relative to thesupport.

The casing 5 is set into the bottom surface of the heel, as clearlyshown in Fig. 2. Positioned within the casing and fixed therein, as bymeans of struck-up portions 9, which enter the material thereof, is adisk-shaped member 10, which is preferably formed of leather, rubber, orsome suitable fibrous material possessed of anti-slipping. qualities.The disk, it will be noted, is confined within the casing 5 so that itcan rotate therewith.

Located directly behind the disk, and fastened to the material of theheel proper, is a semi-circular strip of metal 11, preferably steel,said strip being held in position as by means of the nails or pegs l2;and located directly behind this metallic strip is a similarly formedstrip of yieldable material 13, such for instance as rubber. This stripwhich forms the rear edge of the heel is fastened to the heel proper, asby means of the nails or pegs 14:.

Thus it will be seen that the bottom of the heel is provided with acentrally located revoluble disk 10, the metallic strip 11, and thestrip 13 of softer material, the latter conforming to the rear contourof the heel.

Having thus described my invention, the operation thereof may now beunderstood. During the act of walking the contact of the heel with theground will tend to rotate the disk 10 so that all portions thereof willbe worn evenly, owing to the fact that the disk is rotated. If desired,the disk may also be manually rotated as by inserting a screw driver orcoin in the slot 15, which can be conveniently done by the wearer.

The rearwardly located cushion member 13 relieves the shock due to thecontact of the heel with the ground, and the metallic strip 11 takes thewear that would otherwise be sustained by the cushioning member 13.

As many changes could be made in this construction without departingfrom the scope of the following claims, it is intended that all mattercontained in the above description or shown in the accompanying drawingshall be interpreted as illustrative only and not in a limiting sense.

Having thus described my invention what I claim as new and desire tosecure by Let ters Patent is:

1. In a device of the class described, the combination with a heelhaving a recess formed in its lower surface, a casing rotatively mountedin said recess, means for rotatably supporting said casing, a diskinserted within said casing, and a metallic strip located behind saidcasing and forming a portion of the inclosure thereof.

2. In a device of the class described, the combination with a heelhaving a recess formed in its lower surface, a casing rotatively mountedin said recess, means for rotatably supporting said casing,'a diskinserted within said casing, a metallic strip located directly behindsaid casing, forming surface, a disk shaped member located within saidrecess and adapted to rotate therein, a metallic strip WlllOh conformsto the contour of said disk and forms a portion of the V inclosure, anda cushioning strip located behind said metallic strip. I

In testimony whereof I aflix my signature in the presence of twowitnesses. V
